The /proc filesystem does not actually exist. It does not take up any
disk space. It is created on memory by the kernel. /proc provides
information about the system and its processes. You can find some
information on /proc by typing:
This is a directory containing information about process number 1.
So, /proc/1234 would contain information about process ID number 1234.
this gives you information about your computer's processor type, speed

You can find out what any file contains by typing cat and the filename.
/proc/interrupts shows what IRQs are used, /proc/dma is about
/proc/kcore is an image of the actual memory.
If you are fimilar with the command uptime this is where the
information is taken. This shows how long the system has been
up in seconds. So if typing cat /proc/uptime shows that your
system has been up for 8467200 seconds you can divide it like this:
8467200 / 24 / 60 / 60 = 98 days
